The present invention relates to an opening and closing device of a manual handling pressure extractor cover. More specifically, a power transmission device is installed on the bottom surface of a handle while the original shape of an existing extractor is maintained, and the cover of the extractor can be opened and closed through the rotary force of a charging hand drill or an electric motor. Moreover, a balance pendulum is installed on one side of the cover surface of the heavy extractor, so that a user can easily open and close the cover of the extractor without much force. The opening and closing device of a manual handling pressure extractor by means of the present invention comprises: a cylinder pipe-shaped handle support unit in which a manual handle for opening and closing the cover is inserted and installed on the top thereof and the bottom of which is vertically installed in the center of the cover; a pulley-shaped handle power transmitting unit which is formed at the bottom of the handle; a power transmission supporting unit which consists of a body unit installed to wrap the outer circumferential surface of the handle support unit; and one or more support legs installed to protrude in a widthwise direction in one side of the body unit; a rotary power transmission unit which is vertically installed in the power transmission support unit and has a rotating top so as to transmit rotary power provided from a rotary power transmission means inserted in the bottom thereof; and a V belt which connects the rotary power transmission unit and the handle support unit so as to transmit rotary power. |
